ENDLESS CARRIER.

Specification of Letters Patent. Application filed August 2, 1906. Serial No. 828,969.

Patented Sept. 15, 1908.

To all whom it ma'y'concern.

which it appertains to make and use the same.

My invention relates toimprovements in endless carriers, the objectof the Invention being to so construct the carrier that it shall be strong, durable and easy runnin ,and so that the chain of the carrier will e maintained ina correct straight position between the sprocket wheels.

' A further object is to so constructthe ap, paratus that undue vertical and horizontal play of the carrier will be prevented. 1 7 With these objects'in view, the inventiom consists in certain novel .featuresfif construction and combinations and arrangepointed out in the claims.

In the accompanying drawings; Figure 1 is aplan view of the carrier; Fig. ,2 is aside ments of parts as hereinafter set forth and,

vlew; Fig. 3 isa sectional view; and Fig. 4-

is a view of a portion of the carrier chain. Figs. 5 and 6 are views illustrating an appli cation of my invention.

1 represents suitable framework in which shafts 23 are mounted, and on these shafts, sprocket wheels 45 are secured, for the accommodation of the chain 6 of the carrier. Each sprocket wheel is made with parallel flanges between which the chain passes and these flanges have, notches 7 in their peripheral portions.

Channeled guides 89 are arrangedso as to face each other somewhat spaced apart and secured to the framework as clearly shown in Fig. 3. Through these cooperating channeled guides, the carrier chain passes' The carrier chain comprises links 10 and 11, pivotally' connected together by means of pins 12. Each link 10 comprises two laminated members 1314 spaced apart for the reception of the link 11 between them, said link 11 consisting of a solid bar. Each hinge pin 12 projects beyond the faces of the members of the link 10 and is provided on its ends with rollers 15 which run between the parallel walls of the channeled guides 89 and thus prevent lateral displacement-of the carrier. These rollers 15 also mesh with the notches 7 of the sprocket wheels to propel the carrier. Each link 11 is provided onopposite faces with pintles 16 on which rollers 17 are mounted, said rollers being disposed between the opposing edges of the channeled guides and serving to prevent undue vertical vibration or displacement of the carrier.-

From the above construction and arrangement of parts it will be'seen that the carrier will be accurately guided in its movements and kept perfectly straight between the sprocket wheels, and also that undue lateral or vertical vibration or displacement will be effectually prevented. I

The devices to be conveyed by the carrier are supported by the links 11. In Figs. 5 and 6 of the drawing, I have illustrated the application of my improvements to plating apparatus. When thus used, two conveyers are employed and certain of the links 11 of each 'conveyer are provided with grooved wheels 19, the studs 20 for which, project laterally from a link 11 through the space between the channeled guides. The rod or shank" 21 of a work holder 22 is disposed vertically between two grooved wheels 19 on the superimposed conveyors and said rod or shank is provided with a stud or roller 23 which runs on a cam track 24, so that as the work holder is moved forward by the carrier chains, it will also be raised from one tank 25 and then .deposited in the next tank, by the o eration of the stud or roller' on the shank oi the work holder, running on the cam trackneledgiguides, sprocket wheels, a chain passing over said sprocket wheel and through said channeled guides, and rollers carried by links of the chain between the ends of said Iinks and adapted to run'between the flanges of the resp'ective channe'led guides.

2. In a carrier, the combination with two channeled guides having their flanges projecting toward each other, and sprocket wheels and throu h the channeled guides,

and rollers carried y said chain and ada ted to run between the opposing flanges 0 the respective channeled guides.

3. In a carrier, the combination of channeled guides, sprocket wheels, a chain passing over the sprocket wheels and through said channeled guides, rollers carried by the chain to run within said channeled guides and other rollerscarried by the chain to run between the flanges of the channeled guides.

4. In a carrier the combination of two channeled guides having their flanges projecting towards each other, sprocket Wheels,

a chaln passing over said sprocket wheels and throu h the channeled guides between the paralle flanges of, the latter, and rollers mounted on res ective ends of hinge pins of the chain and isposed to run between the parallel flanges of each channeled guide.

5. In a carrier, the combination of s rocket 'wheels, a carrier chain, two channele guides having their flanges projecting towards each DAVID FELIX BRODERICK.
